Chapter Objectives
  • Use the systems development process outlined in
    this chapter, and the model of IS components from
    Chapter 1 as problem-solving frameworks to help
    you propose information systems solutions to
    simple business problems.
  • Describe and give examples to illustrate how you
    might use each of the steps of the information
    system development cycle to develop and implement
    an e-business system.

Chapter Objectives
  • Explain how prototyping improves the process of
    systems development for end users and IS
    specialists.
  • Identify the activities involved in the
    implementation of new information systems.
  • Describe several evaluation factors that should
    be considered in evaluating the acquisition of
    hardware, software, and IS services.
  • Identify several change management solutions for
    end user resistance to the implementation of new
    e-business applications.

Chapter Summary
  • Business professionals and IS specialists use a
    systems approach to help them develop information
    system solutions to meet e-business needs.
  • Prototyping is a major alternative methodology to
    the traditional information system development
    cycle. It includes the use of prototyping tools
    and methodologies, which promote an iterative,
    interactive process.

Chapter Summary (cont)
  • The application development capabilities built
    into many end user software packages have made it
    easier for end users to develop their own
    e-business applications.
  • The implementation process for IS projects
    involves acquisition, testing, documentation,
    training, installation, and conversion.
  • Business professionals should know how to
    evaluate IT products for acquisition. IT vendor
    proposals should be based on specifications
    developed during the design phase.

19
Chapter Summary (cont)
  • Implementation activities include managing the
    introduction and implementation of changes in the
    business processes, organizational structures,
    job assignments, and work relationships resulting
    from e-business initiatives.
